Remote coding setting method and receiver for a ceiling fan

Abstract

A remote coding setting method is to be implemented by a receiver of a ceiling fan, and includes steps of: (A) when receiving a setting signal during a predetermined time period, obtaining a code length of the setting signal; (B) retrieving, from pre-stored coding data, a piece of coding format information that corresponds to the code length; (C) setting a fan coding format based on the piece of coding format information; and (D) when receiving a control signal after the predetermined time period, decoding the control signal based on the fan coding format, and controlling operation of the ceiling fan based on a result of the decoding.

What is claimed is: 
     
       1. A remote coding setting method to be implemented by a receiver of a ceiling fan, and comprising steps of:
 (A) when receiving a setting signal during a predetermined time period, obtaining a code length of the setting signal; 
 (B) retrieving, from pre-stored coding data, a piece of coding format information that corresponds to the code length; 
 (C) setting a fan coding format based on the piece of coding format information; and 
 (D) when receiving a control signal after the predetermined time period, decoding the control signal based on the fan coding format, and controlling operation of the ceiling fan based on a result of the decoding. 
 
     
     
       2. The remote coding setting method as claimed in  claim 1 , wherein:
 the setting signal contains a plurality of code strings; and 
 the code length is a total number of bits in each of the code strings. 
 
     
     
       3. The remote coding setting method as claimed in  claim 1 , wherein the piece of coding format information is related to coding formats of the setting signal and the control signal. 
     
     
       4. The remote coding setting method as claimed in  claim 1 , wherein the setting signal at least has an address field and an operation field. 
     
     
       5. The remote coding setting method as claimed in  claim 4 , wherein the setting signal further has a reserved field. 
     
     
       6. The remote coding setting method as claimed in  claim 1 , wherein step (C) further includes controlling the ceiling fan to output a completion indication after completion of the setting. 
     
     
       7. The remote coding setting method as claimed in  claim 1 , wherein the predetermined time period counts from when the ceiling fan is started up or when the ceiling fan is powered on. 
     
     
       8. A receiver to be used in a ceiling fan, and comprising:
 a receiver circuit configured to receive a setting signal and a control signal; 
 a memory circuit configured to store coding data that are related to multiple pieces of coding format information respectively corresponding to different code lengths; and 
 a processor configured to perform a remote coding setting method according to  claim 1 .
